Abstract

Abstract:

In the realm of large-scale sporting events, a common issue is monotonous viewing content, the lack of engagement and immersion experienced by audience during pre-game and inter-game intervals. In response to this challenge, a user interaction method using light-emitting smart devices was proposed. This approach involved transforming the audience into a large screen, with each light-emitting device deployed in the audience serving as a pixel on the screen. By equipping every each audience member with a light-emitting smart device, the stadium became a large screen, where the audience could follow the animation and music, wave the light-emitting device in their hands, and interact with the host. The display effect was also synchronized on the big screen in the center of the arena. This solution enhanced the link between the audience members, elevating the viewing experience and imbuing the atmosphere of the game with a sense of enthusiasm. Based on this solution, the spectator screen display system based on light-emitting devices was successfully applied to the ice hockey events of the 2022 Beijing Winter Olympics. The results showed that the system could significantly enhance the spectator experience and exhibited promising potential for application in various areas, including the content display within the arena, information dissemination, and seating guidance.

Key words: virtual simulation, game viewing experience, preview systems, human-computer interaction
